Description For RFIC - PLL Design Engineer

Do you have a passion for invention and self-challenge? Do you thrive with pushing the limits of what's considered feasible? As part of an outstanding team, you'll craft sophisticated, groundbreaking projects that deliver more performance in our products than ever before. You'll work across fields to transform improved hardware elements into a single, coordinated design.

As an RFIC-PLL Designer, you will provide analog and digital PLL solutions for wireless SoC and drive them to mass production for Apple's Wireless Connectivity products. Responsibilities include:

  • Lead design of radio transceiver chains including analog PLLs - VCOs, digital PLLs - DCOs, LOGen, and chain of blocks in RX and TX.
  • Drive radio KPI (power, area, performance) to meet product requirements.
  • Work closely with RF Systems on block-level and high-level specifications of the PLL-LOGen, TX, and RX line-ups.
  • Hands-on design contributions, from concept to actual design, simulations, and extractions.
  • Responsible for the floorplan layout and verification of the design.
  • Provide design versus silicon measurements correlation and compliance with volume production specifications.

You'll be part of the Wireless Radio team, at the center of a wireless SoC design group with a critical impact on getting Apple's groundbreaking wireless connectivity solutions into hundreds of millions of products.

Minimum Qualifications:

  • BS and 3+ years of relevant industry experience.
  • Experience with RF/analog and mixed-signal design in groundbreaking RF CMOS design.
  • Experienced in the design and development of fractional N Synthesizers, Digital PLLs, Analog PLLs, and LO-Gen.
  • Hands-on experience designing TDC, GRO, Digital Filters, Sigma Delta Modulators, Pre-scalers, MMD, DCOs, PFD-CP, and VCOs.
  • Skilled in using Cadence Virtuoso, Spectre RF, Matlab, and EM simulation tools.
  • Familiarity with mixed-signal verification methodologies.

Preferred Qualifications:

  • Direct experience in designing and bringing wireless transceivers into mass production.
  • Extensive knowledge in fractional N synthesizer and LOGen silicon characterization and debugging.
  • Deep understanding of analog, mixed-signal, and RF circuit design.
  • Familiarity with various RF transceiver architectures and their trade-offs.
  • MSEE and/or PhD with extensive experience.

Join us, and you'll help us innovate new technologies that continually outperform the previous iterations!
